The series of reactions is:
4 NH3 + 5 O2 → 4 NO + 6 H2O <span>
6 NO + P4 → P4O6 + 3 N2
P4O6 + 6 H2O → 4 H3PO3
4 H3PO3 → PH3 + 3 H3PO4 </span>
<span>
We multiply the first equation by a number 3 and all the
other equations by number 2, so that we get:
12 NH3 + 15 O2 → 12 NO + 18 H2O
12 NO + 2 P4 → 2 P4O6 + 6 N2
2 P4O6 + 12 H2O → 8 H3PO3
8 H3PO3 → 2 PH3 + 6 H3PO4
Then the overall reaction is:
12 NH3 + ... → 2 PH3 + ...
</span>
<span>So calculating for PH3:
<span>(1.10 g NH3) / (17.0306 g NH3/mol) x (2/12) x (33.9976 g
PH3/mol) = 0.366 g PH3</span></span>

1. Density is calculated by dividing the object's mass by the volume it occupies.
2. The volume may be determined by water displacement method.
3. D = m/v
Substituting the known values,
D = 10.0 g / 15.625 cm³ = 0.64 g/cm³
Answer:
Option D is correct.
Explanation:
Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure because any gas at a higher temperature and a lower pressure will behaves like an ideal gas. for eg.
nitrogen at STP show its behavior as an ideal gas.
When pressure of a gas increased & temperature is decreased then the gas does not follow ideal gas law.
Therefore option D is correct.
